The Atlanta Zoo is planning to expand the land area by 5 acres to preserve the historic facade of the Cyclorama building, and for this to continue they need a very huge amount of money. Luckily, Zoo Atlanta received a historic grant from the Robert W. Woodruff Foundation amounting to $20 million.
“In 25, 50, 100 years from now, Atlantans will look back on the history of Zoo Atlanta and recognize this expansion as a defining moment in our evolution,” said Raymond King, president and CEO of Zoo Atlanta. “It will permanently redefine our future.”
